FIELD OF THE PRESENT INVENTION

The present invention relates to an anti-sagging unit comprising the first anti-sagging unit and the second anti-sagging unit for restoring the sag of the furnishing item.

BACKGROUND OF THE PRESENT INVENTION

The furnishing items such as mattress and cushions of chairs are generally made up of foam. If the foam used in the furnishing items is not of good quality it will deteriorate with time. This deterioration is in regards with the firmness of the foam which get affected with the time. The most affected area of the furnishing item is the one on which the user sits or sleeps frequently. This affected area leads to creation of sag in the foam of the furnishing item. These sags are one of the most common reasons for variety of back & shoulder ailments in the people using them. People who become aware of this problem usually replace the furnishing item with a new one but this is not an option for people with budget constraints. Conventionally, to solve this problem people use to place a book, board or a rug under the sagged area of the furnishing item so as to restore the normal position of the foam but after some time the things kept under the furnishing item starts to prick the back of the user which was highly undesirable.

To address this problem, various inventions have been made in this field to improve the comfort of the user.

In the invention U.S. Pat. No. 6,871,369, inventor proposes a kit comprising three paraboloid shaped inserts made up of resilient foam which restores the sagginess of the mattress. Although, these inserts restores the sags of the mattress but after some time the paraboloid shape of the inserts raises the mattress abnormally and forms lumps in the mattress causing discomfort to the user.

In the invention U.S. Pat. No. 6,665,898, the inventor discloses an inflated device to be placed under the sagged area of the mattress. The mentioned inflated device is to be filled with air using an inflation hose and an air pump device. The disadvantage to this invention is that a small rupture in the inflated device makes it non-functional.

In the invention U.S. Pat. No. 3,319,274, the inventor discloses a body to be placed under the sagged area of the mattress. The convex shaped body enables the restoration of the sagged area. Since, the body is of convex shape it raises the area of the mattress and reduces the sag but after some time the convex shape of the body raises the mattress abnormally and forms lumps in the mattress causing discomfort to the user.

Therefore, there remains a need of such an insert which apart from reducing the sag of the furnishing items also provides comfort to the user even after their long term acclimatization with it.

SUMMARY OF THE PRESENT INVENTION

The main objective of the present invention is to overcome the limitations of the prior arts by providing an anti-sagging unit comprising the first anti-sagging unit and the second anti-sagging unit for restoring the sag of the furnishing item.

In order to achieve the above mentioned objective, the present invention provides an anti-sagging unit comprising the first anti-sagging unit and the second anti-sagging unit, wherein the first anti-sagging unit is placed on the base support and the second anti-sagging unit is place on the first anti-sagging unit & also under the sagged area of the furnishing unit. Since, the length of the second anti-sagging unit is longer than the length of the first anti-sagging unit hence it prevents the first anti-sagging unit to form lumps in the furnishing item even after its prolong use and thus provide comfort to the user & also restores the sag from the furnishing item.
